Hi, wondering if anyone here is familiar with the older B31s? I've just been trying to fit new front wheel bearings and think I made a balls of it. Got them in with a bit of a struggle, the inner sleeve meant I wasn't sure what to fit on to what first. It seemed impossible to fit the second one without putting pressure on the first.Once they were both in the bearings were stiff and notchy. I took them out again and checked them both, they seemed fine, put it all together again and it was still stiff. With a bit of tapping on different bit they eased up, but still didn't seem right. Any ideas where I went wrong?
